CNNVisualize.jl

This Package implements popular CNN Visualization techniques and is built on top of Flux.jl. Most of the models from Metalhead.jl will work out of the box. To visualize custom models look at the documentation.

Implemented Algorithms

1. Gradient Visualizations using Vanilla BackPropagation
2. Gradient Visualizations using DeconvNet
3. Gradient Visualizations using Guided BackPropagation
4. Gradient Weight Class Activation Maps
5. Guided Gradient Weight Class Activation Maps
6. DeepDream
7. Class Specific Image Generation

TODO

1. CNN Filter Visualization
2. Inverted Image Representations
3. Smooth Grad

Some Notes

1. DeepDream Code in this repo is a direct copy of the code in my other repository DeepDream.jl. The code here demonstrates only a small fraction of what is actually implemented in the original repository. For more advanced operations like guided dreams and video generation have a look at the other repository
